Ans) A) Centripetal force will be doubled.
See centripetal force F = mv^2/r
That means centripetal force is directly proportional to the mass of the particle
So, if we double the mass, centripetal force will be increased by twofolds.
So, option A) is correct.
Now, looking at the other options,
B) says centripetal force is unaltered which is incorrect as centripetal force has been altered and increased twofold.
Option C) and D) reduces centripetal force which are also not possible here.
So, only Option A) is correct
Explanation:
total resistance=(2×2)/(2+2)= 1ohms
Answer:
Explained
Explanation:
a) Len'z law state's that the direction of induced current is such that it always opposes the cause it produces.
So, from south pole field lines go away from the loop, so to increase the flux through loop the direction of current must be clockwise.
b)
When the north pole was leaving the loop, the direction of current must be counter clock wise in the loop
